It is real easy to open the case with a screwdriver and then remove the old memory from it’s socket and push the new ones in, you just use your fingers, no tools are needed, and no wires are touched or even connect to it at all, it is just something that is unplugged and is plugged in, in a simple socket.
You can get a friend to help you, I think that is what Joe was suggesting, it would really speed up your computer.
I’m not a techie at all, but I managed to order the correct memory stick for my laptop and installed it. It was like getting a new machine. Boots up quickly, shuts down quick, and surfs just fine now with many windows open. All this for about $32.
